Closed circuit cooling tower calculations.

Of the direct contact devices the most rudimentary is a spray filled tower that exposes water to the air without any heat transfer medium or fill. Cooling towers winter operation free cooling 371 16 kb. Closed loop cooling tower. 0 3 to 1 0 recirculation rate 100.

Flow rate in gpm. The efficiency of this cooling tower system depends on climatic conditions in particular the wet bulb temperature and the relative humidity of the ambient air. Cooling tower with drift eliminator. Cooling tower efficiency calculations.

The mh fluid cooler remains one of the most efficient systems and best choices for industrial and hvac closed loop applications. Closed looped cooling tower is one of the methods of heat transfers. Closed circuit cooling towers operate in a manner similar to open cooling towers except that the heat load to be rejected is transferred from the process fluid the fluid being cooled to the ambient air through a heat exchange coil. Equipment layout manual for cooling towers evaporative condensers closed circuit coolers.

The coil serves to isolate the process fluid from the outside air keeping it clean and contaminate free in a. Bac s product selection software contains performance and technical data for all of bac s evaporative cooling products. 0 01 recirculation rate 100. Cooling tower sizing program.

To my way of thinking a closed circuit cooling tower would look and behave like a refrigeration system with the evaporator doing the process cooling and the condenser located remotely with cooling fins and a fan pulling air across them just like w. Range of cooling in f t1 t2 area wet bulb temperature in f twb the design heat load is determined by the flow rate and the range of cooling and is calculated using the following formula. Heat load btu hr gpm x 500 x. Closed circuit cooling tower calculations.
